you'd need forged piston/rods and enhanced fuel pump, injectors, mass air and tuning to "up the shot"...more 02 requires more fuel...I'd guess you could do a 100 shot with the stock engine...just not for too long

A 100 shot should be fine on the engine. You could probably run a 125 shot just not as often. After that you will need to up the compression and run forged internals.

You can run a 100 shot as long as you take the proper safety precautions. Ie-purge kit, bottle warmer, safety blow down, window switch, w0t switch, spark plugs, timing retard and a proper tune Just remember, nitrous is not a "lets just throw this on" type of kit. That is, unless your into rebuilding your blown engine

You need to have the car tuned to handle the NOS, the stock system should support a 100 shot for a short burst...a lean condition is what will blow your motor, you need to address and engineer that concern into your car...

Good Advice, Man I could imagine how hard one of these cars would pull with a 125 wet shot coming out of an atomizing nozzle right before the throttle body! And I wouldn't run ANY size Kit with the stock fuel pump! I'm only at 50% Duty Cycle at WOT on my stock pump but I'd want piece of mind knowing there's enough flow.
Yeah that Dumbass obviously didn't have the right saftey features installed in his Kit, that car should have had an rpm switch set at about 3700-6000 rpms, he kicked the juice on at too low an rpm and had the Worst Intake Backfire I've ever seen!!
Nitrous on stock 99 cobra?
